Resistance temperature detector formed with a surface installation element construction

A surface installation type resistance temperature detector (RTD) supported on a substrate, which comprises: a resistance stripe arranged on the top surface of the substrate, the resistance stripe having approximately linear resistance temperature coefficients (TCR) in the predetermined temperature measurement range; two top terminals arranged on two corresponding ends of the top surface of the substrate, in which each of the top terminals is connected to one end of the resistance stripe; two bottom terminals arranged on the bottom surface of the substrate, in which each of the bottom terminals is arranged on a place below the top terminals; two edge conductive plates separately arranged on one edge surface of the substrate and connected to one of the top terminals corresponding to the bottom terminals below; and two surface installation type soldering electrodes, in which each soldering electrode forms a conductive layer and is covered on the top terminals, the edge conductive plates, and the bottom terminal
